Prevention of cardiovascular events and death with pravastatin in patients with coronary heart disease and a broad range of initial cholesterol levels

BACKGROUND In patients with coronary heart disease and a broad range of cholesterol levels, cholesterol-lowering therapy reduces the risk of coronary events, but the effects on mortality from coronary heart disease and overall mortality have remained uncertain. METHODS In a double-blind, randomized trial, we compared the effects of pravastatin (40 mg daily) with those of a placebo over a mean follow-up period of 6.1 years in 9014 patients who were 31 to 75 years of age. The patients had a history of myocardial infarction or hospitalization for unstable angina and initial plasma total cholesterol levels of 155 to 271 mg per deciliter. Both groups received advice on following a cholesterol-lowering diet. The primary study outcome was mortality from coronary heart disease. RESULTS Death from coronary heart disease occurred in 8.3 percent of the patients in the placebo group and 6.4 percent of those in the pravastatin group, a relative reduction in risk of 24 percent (95 percent confidence interval, 12 to 35 percent; P<0.001). Overall mortality was 14.1 percent in the placebo group and 11.0 percent in the pravastatin group (relative reduction in risk, 22 percent; 95 percent confidence interval, 13 to 31 percent; P<0.001). The incidence of all cardiovascular outcomes was consistently lower among patients assigned to receive pravastatin; these outcomes included myocardial infarction (reduction in risk, 29 percent; P<0.001), death from coronary heart disease or nonfatal myocardial infarction (a 24 percent reduction in risk, P<0.001), stroke (a 19 percent reduction in risk, P=0.048), and coronary revascularization (a 20 percent reduction in risk, P<0.001). The effects of treatment were similar for all predefined subgroups. There were no clinically significant adverse effects of treatment with pravastatin. CONCLUSIONS Pravastatin therapy reduced mortality from coronary heart disease and overall mortality, as compared with the rates in the placebo group, as well as the incidence of all prespecified cardiovascular events in patients with a history of myocardial infarction or unstable angina who had a broad range of initial cholesterol levels.

Factors contributing to the shortage of nurse faculty : a review of the literature

There is an abundance of literature documenting the shortage of nurse faculty, both in Australia and internationally. This shortage has repercussions for the next generation of nurses, contributes to the overall nursing workforce shortage, and holds implications for the development of nursing research and continued practice development. The literature suggests a multitude of factors contributing to the shortage, including the ageing of current nurse faculty, and an undersupply of doctorally prepared nurses to take their place. To date, most nurse academics come from a clinical background with little preparation for the complex faculty role; despite this there is little exploration of their experiences transitioning to academia. The limited available evidence suggests that this new role may be accompanied by feelings of uncertainty, anxiety and isolation associated with changed responsibilities, an emphasis on scholarly activities and teaching, and the unique culture of the academic environment. The aim of this paper is to provide a critical review of the literature, identify issues relevant to the nurse faculty shortage and provide direction for further research.

A Cardiac Rehabilitation Program to Improve Psychosocial Outcomes of Women with Heart Disease

BACKGROUND AND AIMS Heart disease in women is characterised by greater disability and a higher rate of morbidity and early death after an acute coronary event compared with men. Women also have lower participation rates than men in cardiac rehabilitation. This study sought to describe development of a nurse-directed cardiac rehabilitation program tailored to the needs of women following an acute cardiac event to address their psychological and social needs. METHODS The Heart Awareness for Women program (HAFW) commenced in 2003 with phase I involving development of program elements and seeking validation through consumers and clinical experts. The program was then trialed in an 8-week program in a convenience sample of 6 women. Phase II applied the revised program using action research principles focusing on enabling clinical staff to implement the ongoing program. A total of 54 women participated in this phase, 48 of whom completed baseline questionnaires. A mixed-method evaluation, using questionnaires, interviews, and observation, assessed the impact of the intervention on psychological and social aspects of womens recovery following an acute coronary event. RESULTS Women welcomed the opportunity to discuss their individual stories, fears, and challenges and to derive support from contact with other women. Via health professional facilitation, women were able to develop strategies collectively to address risk factor modification and achieve optimal cardiovascular health. No statistically significant changes in depression, anxiety, stress, cardiac control, role integration, or perceived social support were found; however, descriptive and qualitative findings revealed decreases in anxiety and an increased sense of social support. CONCLUSIONS On the basis of this study, a cardiac rehabilitation program tailored to the needs of women appears to be feasible and acceptable. The efficacy of this intervention to improve health-related outcomes needs to be tested in a randomized, controlled trial.

Perceptions and Experiences of Heart Disease: A Literature Review and Identification of a Research Agenda in Older Women

Background:: Following diagnosis of heart disease women have poorer health related outcomes compared with men. Nursing science lacks well-evaluated interventions to address the specific rehabilitative needs of older women with heart disease. AIMS:: This paper seeks to inform the development of nursing intervention studies by a review of published studies on the experiences and rehabilitative needs of older women with heart disease. Methods:: The CINAHL, MEDLINE, FAMILY and PsychINFO databases were searched, identifying literature published from 1982 and written in English. Keywords used were women, old∗ (old, older) women, elderly women and: heart disease, heart failure, cardiac and rehabilitation. Hand searching of nursing and medical textbooks also occurred. These searches resulted in over 120 articles that met the criteria of describing experiences, perceptions, psychological responses and support rehabilitative needs of older women. Results:: Older women present with symptoms that are different from those derived from a male-dominated research agenda and further there is a paucity of data related to evaluation of interventions tailored to the needs of women. Key themes emerging from the literature review include not only that older women compared with men have a poorer prognosis and experience greater disability moreover they: (1) are at a higher risk of psychosocial distress; (2) have a greater need for instrumental support and social support; (3) have an altered perception of risk; and (4) demonstrate the need for specific rehabilitation programs, tailored to their needs. Conclusion:: Future research should develop and evaluate intervention studies that better meet the unique needs of older women with heart disease. Particular emphasis needs to be on psychosocial aspects, given evidence that identify these are major concerns for women.

Attributes of clinical leadership in contemporary nursing: An integrative review

Abstract Effective clinical leadership is offered as the key to healthy, functional and supportive work environments for nurses and other health professionals. However, as a concept it lacks a standard definition and is poorly understood. This paper reports on an integrative review undertaken to uncover current understandings of defining attributes of contemporary clinical leadership in nursing. Data collection involved a search of relevant electronic databases for a 10-year period. Keywords for the search were ‘clinical leadership’ and ‘nursing’. Ten research papers met the inclusion criteria for the integrative review. Analysis of these studies indicated clinical leadership attributes had a clinical focus, a follower/team focus or a personal qualities focus; attributes necessary to sustain supportive workplaces and build the capacity and resilience of nursing workforces. The small number of research-based studies yielded for the review indicates the need for further research in the area of clinical leadership.

Australian nurses in general practice based heart failure management : implications for innovative collaborative practice

Background: The growing global burden of heart failure (HF) necessitates the investigation of alternative methods of providing co-ordinated, integrated and client-focused primary care. Currently, the models of nurse-coordinated care demonstrated to be effective in randomized controlled trials are only available to a relative minority of clients and their families with HF. This current gap in service provision could prove fertile ground for the expansion of practice nursing [The Nurse in Family Practice: Practice Nurses and Nurse Practitioners in primary health care. 1988, Scutari Press, London: Impact of rural living on the experience of chronic illness. Australian Journal of Rural Health, 2001. 9: 235–240]. Aim: This paper aims to review the published literature describing the current and potential role of the practice nurse in HF management in Australia. Methods: Searches of electronic databases, the reference lists of published materials and the internet were conducted using key words including ‘Australia’, ‘practice nurse’, ‘office nurse’, ‘nurs∗’, ‘heart failure’, ‘cardiac’ and ‘chronic illness’. Inclusion criteria for this review were English language literature; nursing interventions for heart failure (HF) and the role of practice nurses in primary care. Results: There is currently a paucity of data evaluating the potential role for practice nurses in a reconfigured, collaborative health care system. Those studies that were identified were, largely, of a descriptive nature. In addition to identifying the practice nurse as a largely unexplored resource, key themes that emerged from the review include: (1) current general practice services face significant barriers to the implementation of evidence-based HF practice; (2) there is considerable variation in the practice nurse role between general practices; (3) there are significant barriers to the expansion of the practice nurse role; (4) multidisciplinary interventions can effectively deliver secondary prevention strategies; (5) practice nurses can potentially facilitate these multidisciplinary interventions; and (6) practice nurses are favorably perceived by consumers although there is some confusion about the nature of their role. Conclusion: On the basis of this literature review, practice nurses represent a potentially useful adjunct to current models of service provision in HF management. Further research needs to comprehensively investigate the role of the practice nurse in the Australian context with a view to developing effective and sustainable frameworks for clinical practice. In particular, high-level evidence is required to evaluate the efficacy of the practice nurse role compared to current disease management strategies.

Challenges for professional care of advanced dementia.

Qualitative methodology based on action research identified challenges when caring for persons with advanced dementia, as perceived by key professional providers. Data collection was via five focus groups (total n = 24) and 20 follow-up individual interviews. Participants included palliative care, aged care and dementia specialist nurses, medical specialists from an area health service, residential aged care staff and general medical practitioners. Responses emphasized the need for improved knowledge and skills, and clearer policy. Concerns included accurate assessment, especially of pain, owing to the inability of people with advanced dementia to communicate their symptoms. Assessment, managing physical and behavioural symptoms, and communicating with family presented as further challenges. Conclusions are that the need for a palliative approach to care in advanced dementia should be recognized. Aged care staff can deliver palliative care to people with advanced dementia only if the staff receive relevant education and training beyond their generalist competencies.

Patient-centered needs assessment: Rationale for a psychometric measure for assessing needs in heart failure

Determining an individuals unique perspective of an illness experience remains a challenge for clinicians, administrators, and researchers. A range of concepts and psychometric measures have been developed and evaluated to capture this information. These include patient satisfaction, quality of life, and utility measures. Needs assessment as a tool for evaluating perceptions of health status and determining patient satisfaction and treatment plans has been explored in oncology. Studies have demonstrated that a high proportion of patients have unmet needs in relation to activities of daily living, information sources, and comfort. Heart failure (HF), a condition with significant individual and societal burden, mirrors the illness of experience of cancer, as individuals process issues related to prognosis, treatment regimens, and decreased functional status. A needs-based assessment of health status, expectations, and perceptions is patient-centered and has the capacity to not only evaluate current health status but also plan and project care plans. Needs assessment is a dynamic construct rather than a point in time consistent with other assessment modalities, such as quality of life. Multidimensional needs assessment allows for planning and projection of needs, not only on an individual but also a population basis. Implicit in the exploration of needs is an expectation of level of care to be provided, from both the provider and recipient of care. In many instances a misalignment may exist between services and resources available to the individual. This article seeks to provide a theoretical justification for the development of a needs assessment instrument for patients with HF and to discuss the rationale of this method of assessment to create better alignment and resources with patients needs and expectations.

Role theory : a framework to investigate the community nurse role in contemporary health care systems

Nurses’ perceptions of their role are influenced by societal attitudes, government policies and trends in professional issues. Dynamic factors in contemporary health environments challenge traditional nursing roles, in particular those of community nurses. Role theory is a conceptual framework that defines how individuals behave in social situations and how these behaviours are perceived by external observers. This paper reviews the role theory literature as a conceptual framework to explore community nurses’ perceptions of their role. Three theoretical perspectives of role theory have emerged from the literature review: (i) social structuralism; (ii) symbolic interactionism; and (iii) the dramaturgical perspective. These philosophical perspectives provide a useful framework to investigate the role of community nurses in the contemporary health care system.

Cultural Diversity in Heart Failure Management: Findings from the DISCOVER Study (Part 2)

Abstract Self-management is a critical dimension in managing chronic conditions, particularly in heart failure (HF). Knowledge, attitudes and beliefs, relating to both illness and wellness, are strongly influenced by culture and ethnicity, impacting upon an individual’s capacity to engage in self-care behaviours. Effective management of HF is largely dependent on facilitation of culturally informed, self-care behaviours to increase adherence to both pharmacological and non-pharmacological strategies. The Understanding the cultural experiences of individuals with chronic heart failure (CHF) in South East Health (DISCOVER) study is an exploratory, observational study investigating health patterns, information needs and the adjustment process for overseas-born people with HF living in Australia. An integrative literature review was augmented by qualitative data derived from key informant interviews, focus groups and individual interviews. A key finding of this study is that culture provides an important context to aid interpretations of attitudes, values, beliefs and behaviours, not only in illness but in health. While individual differences in attitudes and beliefs were observed among participants, common themes and issues were identified across cultural groups. Data from the DISCOVER study revealed the primacy of family and kinship ties. These relationships were important in making decisions about treatment choices and care plans. Participants also revealed the critical role of the ‘family doctor’ in assisting people and their families in brokering the health care system. In this study, heart disease was considered to be a significant condition but cancer was the condition that people both feared and dreaded the most, despite the high mortality rates of HF. This sample reported that religious and traditional beliefs became more important as people aged and considered their mortality. As HF is predominately a condition of ageing, the information derived from this study will assist clinicians to tailor health care service delivery for older people with / HF, across multiple ethnic backgrounds.
